Grenzhof test site

The Grenzhof test site close to Heidelberg was running until 2018. Since 2003, experiments were conducted on the formerly agricultural field. In 2004, a weather station (Fig. 1) was installed. It measured precipitation, air temperature, relative humidity, air pressure, wind, incoming and outgoing solar, and far infrared radiation. The information is required to assess the soil-atmosphere interaction.

To investigate the soil, at several locations TDR probes (to measure water content) and temperature probes were installed in the soil profile.

In 2009 two areas were set up. The surface above one was kept free of vegetation (until 2012), while for the other grass at a height of a few centimeters was maintained (Fig. 2). Again water content and temperature were measured beneath each.
